From sea level to the top of the atmosphere, a column of air with a 1-m2 cross section weighs 101,000 N.
To find the answer we have to know about the pressure.
<h3>
What is Pressure?</h3>
- The pressure at a point on a surface is the thrust acting per unit area around that point.
- A particular mass of air is contained in a column that rises from the ocean to the top of the atmosphere. Then,
Pa is the atmospheric pressure at the sea level.
- By combining both the equations, we get the weight of air,
Thus, we can conclude that, the weight of air in a column 1-m2 in cross section that extends from sea level to the top of the atmosphere is 101300N.

-- 'Ca' (Calcium) is an element.
-- The proton has a positive charge.
-- Nuclear fusion results in the synthesis of atoms of new elements.
-- H₂O (water) is a chemical compound.
-- Nuclear fission is a decay of the nucleus.
-- The atomic number of an element is the number of protons
in each atom of it.
-- I suppose you're using the Greek letter <span>η ('eta', not 'nu')
to represent the neutron.

I think the answer is b but i cannot confirm cuz this is a challenging question
Answer:
λ = 1360 m
Explanation:
Given data:
frequency of driving nails is given as 1 stroke per second mean at every 0.25 sec she hit the nails
speed of sound is given as 340 m/s
we know that the wave equation is given as
Speed = frequency × wavelength,
v = f × λ
where,
v = speed in meters/second (m/s)
f = frequency in Hertz (Hz)
substituing value to get wavelength of her driving nails
λ = 1360 m
